Johnson is able to box off of the jab, keep it simply and use those fundamentals and natural advantages which is what he did well. Johnson has great balance and feet and would, be able to judge the distance well and read Qawi when he attempts to close the distance, and the jab would help him measure Qawi, get a feel for his rhythm and therefore would help him read Qawi and use his footwork to make Qawi fall short. Qawi is great, but there’s not much you can do when you’re infront of a guy who has those advantages (height and reach) and is able to use them expertly.
